Letters Patent No. 95,7 64, dated October 12, 1869.

IMPROVEMENT IN FANS.

The Schedule referred to in these Letters Patent and making par?.` oxthe same.

To all whom it may concern invention when the fan is unfolded.

Figure 2 is a transverse section of the same when i the fan-leaf isfolded.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a spring and guide-rod incombination with the central head of a fan-leaf, and with radiating armsprovided with guide-slots, catching over pins, which are secured in theframe of the fan, in such a manner, that by pushing the head downagainst the action of the spring, the fan-leaf is folded up by theaction of the slotted arms, and by releasing the head, the fan-leaf isautomatically unfolded by the action of the spring.

In the drawing- The letter A designates a fan-leaf, made of paper,muslim, or any other suitable material capable of being folded up andexpanded, as shown.

Said leaf is secured to a central head, a, which slides in and outbetween the two side-pieces of the frame B, and from which extends a.button, b, through a. slot, c, in one of said pieces, so that said headcan be readily operated.

To the edges of the fan-leaf are secured the radiating arms d, which arerigid, and 'serve to stiffen the fan-leaf, and which are provided withguide-slots e, catching over pins f, which are ligidly secured in theframe B.

As thehead tt is pushed down toward the handle Cof the frame B, the armsd are made to slide over the pins f, and they are finally turned, andthereby the fan-leaf is folded up between the two side pieces of theframe B, as shown in iig. 2, and as the head a is moved out away fromthe handle C, the arms d are reversed,and the fan-leaf is unfolded, asshown in fi r. 1.

From the head a extends a rod, l, which is provided with a collar, g,that presses against the end of a spring, h, enclosedin'the hollowhandle O, andasthe head 1s pushed downtoward the handle, the spring iscompressed. In this Iposition the head is retained by a spring-catch, t,which is secured to the outside of the frame B, and which catches into ahole Vin a plate,l i

j, fastened to the head.

By pressing on the spring-catch, the head a is released, and the springh carries the same back to the position shown iu fig. 1, causing thefan-leaf to unfold automatically.

When the fan-leaf is folded, and the head retained by the spring-catcht', the fan can be conveniently carried in the pocket, and by a slightpressure on the spring-catch, the fan-leaf unfolds, and the fan is readyfor use.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with the head a, slotted arms d, and fan A, of thespring h and rod l, substantially as and for the purpose described.

This specification signed by me, this 5th day of August, 1869.
